摘要: 交通廊道对城市空间有不同程度的割裂。在城市生态复兴下，缝合交通廊道的割裂成为建立绿色基础设施生态系统服务的重要基石。“生态语境下交通廊道对城市空间割裂程度研究模型的建构”在泛生态的视角下，以交通廊道为研究对象，从缝合环境生态、空间生态、功能生态、文化生态等城市典型生态需求出发，通过引入空间句法分析，建构研究交通廊道对城市空间割裂程度定量表达的模型，为城市生态复兴下绿色基础设施空间重塑、缝合的设计及策略提供参考依据或研究基础。最后以北京某城市快速路路段为对象，运用成果模型进行例证。
Abstract: Urban space is inevitably divided with varied degrees by built transportation corridor. Under the rejuvenation of urban ecology, to sew up the divided urban space caused by transportation corridor has increasingly become the key basis to establish ecosystem services of green infrastructure. The article aims to structure the framework of divided degree on urban space and explore the quantitative expression via spatial syntax which presents the divided degree on urban space by built transportation corridor. Based on the demands of urban ecosystem including environmental ecology, spatial ecology, functional ecology and cultural ecology, and inspired from multi-ecological function, both the framework and quantitative expression are expected to contribute for spatial reconstruction of green infrastructure and design strategies to sew up the divided urban space, and eventually to serve for urban ecological rejuvenation. It is one expressway in Beijing that is chosen as case study to set an example for quantitative expression about divided degree of urban space.
